Android project there is no output dir after gradle build success?

I am learning Gradle for Android recently. For learning impressively, i create all android application files manually.
my project dirs as below
package name : com.wonbin.gradledemo
project build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
}
}
allprojects {
repositories {
jcenter()
}
}
app module build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "com.wonbin.gradledemo"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
testInstrumentationRunner "adroid.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
debug {
}
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
}
}
lintOptions {
htmlReport true
htmlOutput file("lint-results.html")
}
}
dependencies {
compile fileTree(dir:'libs',include:['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',{
exclude group: 'com.android.support',module: 'support-annotations'})
compile 'com.android.support:appcompat-v7:23.4.0'
testCompile 'junit:junit:4.12'
}
./gradlew build is successful and there are 'intermediates' and 'generated'
dirs , but no outputs dir, i don't know what to do!
Thanks a lot!

You need not only to build, but to assemble it as well.
To do this you can run a gradle task
assembleDebug
Or use Build -> Build APK main menu item

Gradle aar library dependecy in module: failed to resolve

I'm a newbie with gradle and I'm having a dependecy problem. I have the follow project structure:
-MyApp
-MyAppLibrary
-MyAppPro
-MyAppFree
-ThirdPartyLibraryWrapper
--libs\ThirdPartyLibrary.aar
Both MyAppPro and MyAppFree depend on MyAppLibrary, which depends on ThirdPartyLibraryWrapper. As the name suggests, ThirdPartyLibraryWrapper is a wrapper on an external library, namely ThirdPartyLibrary.aar.
This is my configuration:
build.gradle MyAppPro
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.example"
minSdkVersion 8
targetSdkVersion 22
}
buildTypes {
release {
minifyEnabled true
proguardFiles 'proguard.cfg'
}
}
}
dependencies {
compile project(':MyAppLibrary')
}
build.gradle MyAppLibrary
apply plugin: 'com.android.library'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
minSdkVersion 8
targetSdkVersion 22
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
buildTypes {
release {
minifyEnabled true
proguardFiles 'proguard.cfg'
}
}
}
dependencies {
compile project(':ThirdPartyLibraryWrapper')
compile 'com.squareup.picasso:picasso:2.5.2'
}
build.gradle ThirdPartyLibraryWrapper
apply plugin: 'com.android.library'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
minSdkVersion 8
targetSdkVersion 22
}
buildTypes {
release {
minifyEnabled true
proguardFiles 'proguard.cfg'
}
}
}
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
compile(name: 'ThirdPartyLibrary-0.1.0', ext: 'aar')
compile "com.android.support:support-v4:22.0.0"
compile fileTree(dir: 'libs', include: 'volley.jar')
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.3'
}
When gradle sync completes, I have got this error:
MyApp/MyAppFre/ build.gradle: failed to resolve ThirdPartyLibrary-0.1.0
MyApp/MyAppLibrary/ build.gradle: failed to resolve ThirdPartyLibrary-0.1.0
MyApp/MyAppPro/ build.gradle: failed to resolve ThirdPartyLibrary-0.1.0
Can someone help me figure out where is the issue?

The other projects are seeing that the :ThirdPartyLibraryWrapper project depends on an artifact called ThirdPartyLibrary-0.1.0:aar. Java (and Android) libraries do not bundle their own dependencies together - instead, they simply publish a list of their dependencies. The consuming project is then responsible for loading not only the library it directly depends on, but all of the libraries that library depends on.
The net effect of this is that :MyAppFree is loading in :ThirdPartyLibraryWrapper, then seeing that :ThirdPartyLibraryWrapper depends on ThirdPartyLibrary-0.1.0:aar and so thus trying to load that in as well. However, :MyAppFree doesn't know where ThirdPartyLibrary-0.1.0:aar lives.. and so it fails.
The solution will be to place similar repositories blocks in all your other projects. Try this:
repositories {
flatDir {
dirs project(':ThirdPartyLibraryWrapper').file('libs')
}
}
Using the project(...).file(...) method will free you from having to hardcode paths, and will instead use the Gradle DSL to resolve the filesystem path by looking up the project and having it do the resolution dynamically.

android- Gradle: An issue occurred configuring root project android studio

I migrated from eclipse to android studio. I've create a new project and I want to run it on genymotion. When I press run icon, it begins to compile and give me this error :
Error:Gradle: A problem occurred configuring root project 'Khabar'.
> Could not resolve all dependencies for configuration ':classpath'.
> Could not resolve com.android.tools.build:gradle:1.1.0.

This is some parts of my build.gradle :
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "example.ir.khabar"
minSdkVersion 8
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
build.gradle in root :
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "example.ir.khabar"
minSdkVersion 8

}
buildTypes {
release {

}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:20.0.0'
compile files('libs/universal-image-loader-1.8.4-with-sources.jar')
}
Could you help me? my gradle version is gradle-2.2.1-all

For me, the solution was to add the http url for jcenter, instead of https:
buildscript {
repositories {
jcenter {
url "http://jcenter.bintray.com/"
}
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

In addition to Al's answer, I also had to put the url inside allprojects:
allprojects {
repositories {
jcenter {
url "http://jcenter.bintray.com/"
}
}
}

I was having the same issue on Ubuntu Mate 18.04. I was able to fix it by replacing ibm-java80-jdk & ibm-java80-jre with openjdk. Also, I did update my DNS to cloudflare DNS. But I don't think it had anything to do with the fix.

add google() in your gradle inside the repositories section will solve your problem..
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
}
}
allprojects {
repositories {
jcenter()
}
}

Please, help

Please check your build.gradle and make sure that the mavenCentral reposority is included. Your file should look something like this:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.9.+'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
android {
compileSdkVersion 19
buildToolsVersion "19.1"
defaultConfig {
minSdkVersion 15
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:support-v4:19.1.+'
compile 'com.google.android.gms:play-services:4.4.52'
}

}
also I have removed the miniSDKVersion and targetSDKVersion from AndroidManifest.xml
can someone help me to solve this error.

android method in project gradle file is not needed.Try to remove it.

Add top of your project build.gradle file:
apply plugin: 'com.android.application'
